Ingredients
Scale
Sweet Potato Mixture
- 3 Medium Sweet Potatoes
- 1 Large Egg
- 1/4 Cup Butter, melted
- 1 Pinch Salt
- 1/4 Cup Granulated Sugar
- 1/3 Cup Brown Sugar
- 1/2 teaspoon Cinnamon
- 1/2 teaspoon Vanilla Extract
- 2 Tablespoons Milk or Heavy Cream (any milk will do)
Topping
- 2 Cups Mini Marshmallows
- 1/3 Cup Butter, cold and cut into cubes
- 1/2 Cup All-Purpose Flour
- 3/4 Cup Brown Sugar
- 1/2 teaspoon Cinnamon
- 1/2 Cup Panko Bread Crumbs
- 1/4 Cup Graham Cracker Crumbs
Instructions
- Prepare Sweet Potatoes: Peel and dice the sweet potatoes. Boil or steam them until tender, about 15-20 minutes, then drain well.
- Mash Sweet Potatoes: In a large bowl, mash the cooked sweet potatoes until smooth. Add the egg, melted butter, salt, granulated sugar, brown sugar, cinnamon, vanilla, and milk or cream. Mix thoroughly until all ingredients are well combined and the mixture is creamy.
- Make the Topping: In a separate bowl, combine the cold cubed butter, all-purpose flour, brown sugar, cinnamon, panko bread crumbs, and graham cracker crumbs. Use your fingers or a pastry cutter to blend the mixture until it resembles coarse crumbs.
- Assemble the Casserole: Preheat your oven to 350°F (175°C). Transfer the sweet potato mixture into a greased baking dish and smooth the top evenly. Sprinkle the crumb topping mixture over the sweet potatoes, then evenly distribute the mini marshmallows on top.
- Bake: Place the casserole in the oven and bake for approximately 25-30 minutes, or until the marshmallows are golden brown and the topping is crisp.
- Serve: Remove from the oven and let cool for a few minutes before serving to allow the casserole to set slightly. Enjoy warm as a delicious side dish for your meal.
Notes
- To save time, you can bake whole sweet potatoes until soft and then scoop out the flesh instead of boiling.
- Use full-fat milk or heavy cream for a richer texture, but any type of milk will work.
- For a gluten-free version, substitute panko bread crumbs and all-purpose flour with gluten-free alternatives.
- Watch the casserole carefully in the last few minutes of baking to prevent the marshmallows from burning.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven for best texture.
